It’s hard to believe COP28 is upon us. Kicking off tomorrow (11.30) and concluding 12.12, it’s sure to be a full few weeks of sharing, live streams, and interesting takes.

We’ve been excited to see a few Peer Network members represented as attendees in Architecture 2030’s (in-person and virtual) delegation.

At Living Future last week a woman from Google asked about cost comparisons and I shared that the City of Santa Monica conducted a study analyzing the costs of a prototypical mixed-use project for a Living Building vs. LEED v4 Platinum vs. code compliant (Title 24, part 6).

The 209 committee plans to release it for a 3rd public review and hopes to finalize it in late winter or early spring. I'm just trying to track down one of the earlier verisons of the document... Read more

Folks -anyone know if the 179D Commercial Buildings Energy Efficiency Tax Credit will be renewed for this year? The DOE website only references renewal on Jan 1, 2017... I am not holding my breath, but curious if anyone else has heard one way or the other. Thanks!

Hi SAL friends,

As some of you have heard by now, we've decided to shut down this Peer Network.

After several years of trying, we have not managed to activate it as we had hoped. Given the urgency of the collective action we need to transform the building industry into a force for good in the world, we all need to focus our... Read more
